Production Introduction


The Radiant Solar Heating System integrates multiple components to deliver efficient heating and hot water solutions for homes, villas, and commercial buildings. The system includes a hot water storage cylinder, solar heat pipe collectors, a pump station, and an expansion vessel.


At the core of the system are solar heat pipe collectors that capture sunlight and transfer the energy to a coil heat exchanger inside the water tank. The system is equipped with glycol fluid circulation to prevent freezing, making it ideal for areas with cold winters. The intelligent solar controller automatically adjusts the system based on the temperature difference between the collector and the water tank, ensuring optimal performance.

Solar radiant heating system working principle


two coil split system installation instruction


Adopt the temperature difference circulation, controller operates whole solar water heater system automatically.


1. Pump will start circulation when temperature difference between solar collector and water tank reaches the set value.

2. Pump will stop circulation once the temperature difference lower than set value.

3. The circulation pump makes heat-conducting liquid circulate automatically

4. The heat-conducting liquid transfers heat to the water tank by a coil heat exchanger.

5. The solar thermal panel will collect energy from sunlight to heat water; there is electric heating element inside water tank, for backup in cloudy or rainy days.


The split solar water heating system with 2 coils heat exchanger, not only supply hot water for family, also it could work with floor heating, radiator heating or swimming pool heating.

The vacuum tube solar collector consists of solar evacuated tubes. It is higher efficiency and lower heat loss than flat plate solar collectors when used in extremely cold winter.

The Solar collector tube has a copper heat pipe and aluminum fin inside. The heat pipe condensers transfer heat to the solar collector manifold very fast. If any glass vacuum tube damage will not influence whole system working.  


FAQs


Q: How does the system provide both hot water and room heating?

A: The system’s dual functionality provides hot water for daily use, while the radiant heating system can be connected to floor heating or radiators for space heating.


Q: Can this system be installed on any roof?

A: Yes, the solar heat pipe collectors can be installed on flat roofs, pitched roofs, balconies, and walls, offering flexibility for various building structures.


Q: Is there any backup heating in case of cloudy days?

A: Yes, the system includes an electric heating element inside the tank, which can be activated during cloudy or rainy days to ensure hot water availability.
